Key result
Patient warming blankets can cause ECG artefact, risking unnecessary procedures if external electrical interference goes unrecognized.
Why the study?
Electrocardiographic artefacts are common and can lead to misinterpretation of heart rhythm and unnecessary procedures, with various sources of interference including external devices.

Highlights the importance of recognizing ECG artefacts caused by external devices like warming blankets to prevent unnecessary diagnostic and interventional procedures.
In electrocardiography, an electrocardiographic (ECG) artefact is used to indicate a misleading or confusing alteration in data or observation not arising from the heart. Although technological advancements have produced monitors that may provide accurate data and reliable heart rate alarms, interferences of the displayed electrocardiogram such as (but not limited to) electrical interference by outside sources, electrical noise from elsewhere in the body, poor contact and machine malfunction continue to occur. Artefacts are extremely common, and knowledge regarding them is necessary to prevent misinterpretation of a heart's rhythm, which can often lead to unnecessary and unwarranted diagnostic and interventional procedures. Here we report a case of ECG artefacts that occur owing to a patient's warming blanket and its consequences.

Misra et al. (2018) conducted a case report in Electrocardiographic artefact (n=1). Patient's warming blanket was evaluated on Electrocardiographic artefact. A patient's warming blanket caused an electrocardiographic artefact, highlighting the need to recognize external electrical interference to prevent unnecessary procedures.
